The Cost of a Toxic Team Member

One person can change the atmosphere of an entire workplace, for better or for worse.

Every organisation will occasionally employ someone who struggles, has a bad day or needs additional support. That’s part of being human. But there is a difference between someone having a difficult period and someone whose ongoing behaviour consistently damages the people around them.

A toxic team member doesn’t just affect productivity. They can quietly undermine morale, increase staff turnover, place additional pressure on managers and ultimately impact the quality of care being delivered.

Ignoring the issue rarely makes it disappear.

What Does a Toxic Team Member Look Like?

Toxic behaviour isn’t always loud or obvious. Sometimes it’s the colleague who constantly complains but never offers solutions. It may be someone who spreads gossip, creates conflict between colleagues or resists every new idea. Others may regularly blame everyone else for mistakes, refuse accountability or bring negativity into every shift.

Over time, these behaviours become exhausting for everyone else.

The Hidden Cost

Many employers understandably focus on salary costs when considering the value of an employee. However, the true cost of toxic behaviour extends far beyond payroll.

Managers often spend hours dealing with complaints, mediating disagreements and attempting to repair damaged working relationships. High-performing employees may begin looking elsewhere because they no longer enjoy coming to work.

Absence levels can increase as stress rises, and recruitment costs grow as experienced staff leave. Perhaps most importantly in healthcare and social care, workplace culture directly influences the quality of patient and resident care.

When teams communicate well, support each other and feel psychologically safe, outcomes tend to improve. When relationships break down, everyone feels the impact.

Why Good People Leave

People often say employees leave organisations because of money. While pay is important, research consistently shows that workplace culture, leadership and relationships play a significant role in whether people stay. A single difficult colleague can make an otherwise excellent workplace feel draining.

If leaders repeatedly ignore poor behaviour, the message received by the rest of the team is simple:

“This behaviour is acceptable.”

That can be incredibly demoralising.

The Leadership Challenge

Many managers avoid difficult conversations because they don’t want conflict. Healthcare leaders are naturally caring people, and giving honest feedback can feel uncomfortable. But avoiding the issue often allows problems to grow.

Addressing concerns early, setting clear expectations and documenting conversations fairly gives employees the opportunity to improve before behaviours become entrenched. The goal should never be punishment. The goal is creating a healthy, respectful workplace where everyone can succeed.

Building a Positive Culture

Creating a positive culture isn’t about expecting everyone to agree all the time. Healthy teams challenge ideas, discuss problems and learn from mistakes. The difference is that they do so with respect.

Leaders can strengthen culture by:

• Recognising positive behaviours as often as performance.
• Encouraging psychological safety so staff feel comfortable speaking up.
• Addressing poor behaviour consistently and fairly.
• Supporting wellbeing before people reach burnout.
• Celebrating teamwork rather than individual heroics.

Culture isn’t built during annual away days. It’s built through the everyday conversations managers choose to have—or avoid.

Questions Every Manager Should Ask

If you’re responsible for leading a team, it’s worth reflecting on a few simple questions:

• Do people genuinely enjoy coming to work?
• Are difficult behaviours being addressed consistently?
• Would my best employees recommend this organisation to a friend?
• Do staff feel safe to raise concerns?
• Am I recognising positive behaviours as much as I notice negative ones?

Small improvements in culture can have a significant impact on staff wellbeing, retention and ultimately the quality of care delivered.

Editor’s View

Most organisations don’t lose their best people overnight. They lose them one frustrating shift at a time.

A difficult colleague who is never challenged, a manager who is too busy to listen, or a culture where negativity becomes normal can quietly erode even the strongest teams. Investing in culture isn’t a “nice to have”, it’s one of the smartest investments any healthcare organisation can make.

After all, people rarely remember every policy or procedure, but they never forget how a workplace made them feel.
